What Are Butter-Canned Potatoes?
Butter-Canned Potatoes (Pressure Cooker Method) are potatoes preserved in jars with butter, herbs, and optional onion. The jars are pressure canned to safely preserve low-acid foods while creating a flavorful ready-to-use pantry ingredient.
The butter creates a creamy base while oregano and onion add depth and savory aroma. These canned potatoes are ideal for:
- Breakfast hash
- Roasted skillet potatoes
- Soup starters
- Quick side dishes
- Camping meals

Important Safety Note
Potatoes are a low-acid food, which means proper preservation requires pressure canning to avoid the risk of botulism. Always follow safe canning practices and use tested pressure canning methods.
